RAIL-CHAIR.

To'aZZ whom it may concern:

Be it known that I, ROBERT SAMUEL Ronnn'rs, a citizen of the United $tates, residing at New Orleans, in the parlsh of Orleans and State of Louisiana, have invented new and useful Improvements in Rail-Chairs, of which the following is a specification.

The present invention comprehends the provision of a rail chair designed to possess maximum strength and durability for supporting the weight of the rolling stock, and

at the same time affords the desired yieldsite strength to support the weight of the rolling stock.

Another object of the invention resides in the provision of means whereby the bolts are relieved of undue strain under tendency of the rail to move laterally.

The nature and advantages of the invention will he better understood when the following detail description is taken in connection with the accompanying drawings, the

invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this specification like numerals of reference indicate similar parts in the several views and wherein Figure l is a top plan view.

Fig. 2 is a side elevation.

Fig. 3 is a longitudinal sectional. view taken on the line 33 of Fig. 1.

Fig. 4- is a transverse sectional view taken on the line 44 of Fig. 1.

Fig. 5 is a detail view of one of the attaching plates.

Fig. 6 is a detail view of one section of a chair.

Referring to the drawings in detail, 10 indicates the railroad tie of the ordinary well known construction which is embraced by Specification of Letters Patent. Pate t d N 30 1920 Application filed. November as, 1919.

Serial No. 341,074.

a The depending portion 13 of each section is provided with openings through which suitable fastening elements are driven into the tie for holding the chair in position thereon.

The meeting edges of the horizontal portions of the respective sections, are reduced and overlapped as indicated at 14. Each overlapped portion is provided with a tongue and groove 15 and 16' respectively which are associated when the sections are over-lapped in a manner disclosed in Fig. 4. The chair is of course preferably constructed from metal, and each section is provided with openings 17 through which the fastening bolts 18 are driven for securing the rail upon the chair in a manner to be hereinafter more fully described. Each chair section is formed with central depressed portions 19, which when the sections are associated unitedly define a channel underlying the base of the rail as shown in Fig. 3. Each section is formed with a rib 19 disposed transversely and centrally of the depressed portion 18, these ribs being arranged in alinement when the sections are associated. The ribs 19 are also disposed immediately beneath the base of the rail in vertical alinement with the web 20 thereof, so as to afford the chair maximum strength to support the weight of the rolling stock. It will be noted however, that the opposite longitudinal edges of the base of the rail are disposed upon the chair at opposite sides of the channel and consequently the rail is permitted by reason of this construction to yield under the weight of the rolling stock in a desired manner. Each section at opposite ends of the horizontally disposed portion is formed with a shoulder 22, these shoulders being spaced an appreciable distance from the channels 18.

Attaching plates 23 are employed for securing the rail upon the chair, each plate including a reduced portion to overlap the base of the rail, while the opposite longitudinal edge of each plate bears a ainst the shoulders 22 of the chair sections. By reason of this construction, the spikes 18 which pass through the openings 26 in the plate and also through the openings 17 in the chair, are

relieved olziui'cli-ie'strain ma tendency of r the rails to move laterally. This arrangement obviously adds to the general strength and durability .(sfithe el-iair in its entirety.

iVhile it is believed that from the forc going description the nature and advantages of the invention will be readily apparent,T desire to have 1 1t understood that I do not "limit myself to the exact .constr-uctionand arrangement of parts disclosed and that such changes-may he i resorted to I when desired =as fallavithin the scope ofwhat is claimed.

' .Havingtth-us. described my invention What I claimnewis I 1 FA railchair comprising a pair: of substantially .l -shaped :sections having their meetingedgcseoverlapped, means 2 for securmg.- sardsectlons to; the tie, each SGCl110ILl1&"- mg; a central depressed portion :Lrnitedly dea channel disposed immediately be- T neath the base of the ra1l, .andia rib arranged transversely ofreach sectien and centrally di'sposedxwith respectito the depressedportionafor the purpose specified.

A rail; chair comprising two A substanyi Leshaped: sections,l having their .adja cent edges reduced and overlapped, means "for securing said sections to the tie, said overlappc'diedges (if the respecti've sections having a tongue and groove connection, said sections having alined depressed portions underlying the base of the rail, and ribs arrangedi-n said depressed portions: to: engage lthehaserofithera l in alinement with the uponssaid chair-each having a; portion overthe base -.-of the rail, bolts passed lireugh said plates and chair for securing therailtotlzmetie,v and the opposite edges of sairl plates bearing against said shoulders to relieve the bolts of undue strain as specified. 7 In testimony vvhereofl-afiix my signature.
